I got bad chip on my Quadro FX3700M, it's G92-985-A2. I was wondering how to find latest revision of this chip if someone can tell me, because I heard that a lot of those G92-985-A2 chips are faulty for some reason and I was planning to buy new one but this time latest revision so that I can avoid problems assuming they fixed it in that latest revision.

anyone ?
Forgot to mention that gpu is on my laptop HP 8730w. -
Re: Laptop GPU Chip info.
On the chip there is a date of manufacture, but it is very difficult to find a truly new chip, most chips are Remarked or preserved in poor condition.
In addition , a new chip is more expensive than the entire cardComment

Re: Laptop GPU Chip info.
anyone can tell howto know the bad gpu. what measurement on chip?Comment

Re: Laptop GPU Chip info.
specifying that all tests do not provide a definite answer,
If the chip is not soldered you can measure the VCC inputs respect to ground or if the pads are hard to find, measure whether the capacitors are shorted.
Do not take measurements with diode test but in ohms.
If the chip is welded, then a possible short can come from the power lines that must be disconnected.
However that is the case where the GPU chip is seriously damaged, and probably the motherboard not turn on, if there are internal connections that are disconnected randomly , the only way to test the chip is to use a test socket with a dedicated motherboard.Comment

Re: Laptop GPU Chip info.
In recent years, I tried to buy from different vendors.
There are chips that are easily damaged than others, especially if are handled many times, for example , I never buy an 216-0752001. I always prefer to take the chip from a motherboard that has other problems.
For the reason that I know where it comes from and I prefer to do a reballing with the "tin lead" balls and not lead free. This is Because it is easier to solder (without having to use a very professional soldering station) and free "pad ball pad" is stronger.
All chips that I purchase are converted to lead-tin.
One of the most popular vendors is e-best_trade (http://www.ebay.it/itm/1-Piece-New-N...94082881?hash= item3f364ef141: g: bWIAAOxyItRTdtJM) the price is not low.Last edited by jasko_jacker; 12-24-2016, 08:33 AM.Comment

Hello, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -

To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
